Statement of problem. The proper materials of attachments for implant retained overdenture are unknown, such as the correlation between retention and abrasion, as well as the types of materials that are suitable for patrix and for matrix individually. Purpose of this study. The aim of this study was to select a proper clinical attachment system for a successful treatment as well as patient satisfaction. Methods. Retention and abrasion of 14 commercial attachments were measured during 15,000 removes. Results. A retentive part (matrix) which requires elasticity has to be made of gold while the patrix part which does not require elasticity has to be made of titanium. This gold matrix / titanium patrix combination showed the most retentive force and the least retention loss.

The effects of characteristics of community pharmacists on consultation time for prescription (RX) and nonprescription drugs (nRX) were investigated. A crosssectional descriptive design was established with a self-administered anonymous mail survey. Response rate was 52%. Significant pharmacists' factors related to having less than 3 minutes consultation for RX were one's dispensing duties exceeding 50%, low satisfaction with one's own level of consultation, working at the pharmacies nearby clinics, or shorter duration of consultation time for nRX. Consultation promoting conditions should be built up for the provision of sufficient consultation.

This study examines and analyzes residential environment and factors with partial region of Chungjang-dong, Dong-gu, Gwangju based on land register and questionnaire. Consequently, most of residents are in their forties or over and working at downtown or place near it. It is found that rate of their own house is high and they live in the current house over 10 years. Residential factors at downtown area include its convenience, distance to workplace, convenient transportation and easy use of cultural and commercial facilities, but their consciousness of residence shows a low satisfaction with children education, air pollution, noise, parking facilities, green zone for making community, resting place, sunshine, view and privacy.

According to analysis of responses to the user's demand of theological seminary libraries, the best category of demands is ‘Circulations’ and acceptancy is ‘Electroic Collections.’And the highest type of acceptancy is ‘Improvement of Services.’It is necessary to raise the current acceptancy rate of 49.6％ up to 70∼80% which leads to high level of user satisfaction in the university libraries.

The engineering college in Yonsei University started the RCP(Residential College Program) at Song-do International Campus in 2013. Every first-year engineering student is required to live on-campus at their first semester. They had integrated educational experiences combined with extracurricular community activities as well as curricular activities. The residential learning communities were to decrease the number of students in probation and enrich campus culture. The living and learning communities could help students achieve academic success and to lower the rate in dropping. We ran a survey over the students' satisfaction on RCP. Academic achievement and retentions were compared between the ones in 2011 and 2013.

The purpose of this study is to overview and analyze the commercial document delivery systems. to this end, the study first compared the current systems under three headings, that is, non-collection-based systems(Infotrieve, OCLC, UnCover, BIDS, Swets & Zeitlinger, Kyobobook), collection-based systems(EBSCO, ISI, UMI, BLDSC, CISTI, INIST, NCSI, JICST, KINITI), and specialized collection-based systems(Engineering Information Inc., IEEE/IEE, BIOSIS, CAS, NAL, RSC, TWI, ADONIS). Next, the study analyzeed the advantages and disadvantages of each system, based on the four performance criteria : scope of inventory/journal coverage, turnaround time, delivery ost and payment options, reliability and satisfaction rate.

This study was conducted to explore the relationship between the efficiency and its organizational determinants of tile Community Mental Health Centers(CMHCs). Data are obtained from 81 personnel of 27 CMHCs from Sept. to Oct. in 1999(19 in Kyunggi province, 7 in Seoul City and 1 in Chunchon, Kangwon province). Major findings of this study are as follows. 1. DEA is a mathematical programming technique that optimizes the relative efficiency ratio of inputs over outputs for each decision-making unit(DMU). It produces a summary scalar efficiency ratio for each DMU of CMHCs. It assessed multiple inputs and multiple outputs simultaneously, and compared to specific peer group of CMHCs. 2. Organizational determinants of DEA efficiency of CMHCs we proved as advertisement(＋), location of CMHCs(in public facility)(＋), area of facility(＋), period of operation(＋), job satisfaction(＋), clarity of work-role(vague), cohesion(－), rate of certified personnel(＋), number of referral(＋), and voluntary service time(－).

In this paper, we propose the database design for skill learning service through the internet from the viewpoint of service engineering. This paper we describe the outlines for a design theory for skill learning service, which can lead to the satisfaction of both learner and instructor. Compared to other services, motion control learning takes a considerable amount of time, and this leads to a difficulty for learners to rate the quality of the service as well as for the instructors to provide consistent quality and standard of teaching. To solve these problems, we use a relational database with MongoDB which is an unstructured database allowing to flexibly incorporate the demands of both learner and instructor into the database itself.

Personal media centered on blogs, Twitter, and Facebook has opened up a personal broadcasting area while meeting platforms such as YouTube and Africa TV. Due to the many advantages and disadvantages of personal broadcasting, a study on it was necessary and statistical survey was conducted. The study conducted opinion survey of 118 university students on personal broadcasting. As a result, we are getting news using smartphones and mainly watching videos through YouTube, and watching videos type in the order of games, music videos and sports. Satisfaction rate of video was 72.4%, 80.2% of survey did not use paid services, experiences about personal broadcasting was 96.6% and 90.5% of survey the prospect of person broadcasting of the opinion that "it will be expanded". The first thing we want to be improved in personal broadcasting is the prevention of abusive language and hate speech. Second, we were reluctant to sensational content. Third, the survey results are the improvement of excessive advertising.

Midshaft clavicle fractures are the most common fracture of the clavicle accounting for 80% of all clavicle fractures. Traditionally, midshaft clavicle fractures are treated with conservative treatment even when prominent displacement is observed; however, recent studies revealed that nonunion or malunion rate may be higher with conservative treatment. Moreover, recent studies have shown better functional results and patient satisfaction with surgical treatment. This review article provides a review of clavicle anatomy, describes the current clavicle fracture classification system, and outlines various treatment options including current surgical options for clavicle fracture in adults.
